Answer:
48 children performing.
Step-by-step explanation:
Well all you do is divide 144 by 3 and you will get the answer of 48.
The formula you should use is Area = 1/2bh, in other words, area equals half times base times height. Now, substitute everything in, the equation should now be 221.16 = 1/2*b*29.1. This simplifies into 221.16 = 14.55b, now divide 14.55 on both sides, which leaves us to 15.2 = b. However, don't forget the units, which the answer (length of base) should be 15.2 in.^2.
3-4x=-6x^2
+6x^2=+6x^2
_____________
